Case Reports
Bilateral subdural hematoma following implantation of intrathecal drug delivery device.
To report a case of bilateral subacute subdural hematoma following implantation of intrathecal drug delivery device. ⋯ Medical and nursing staff dealing with intrathecal therapy should be aware of this potentially severe complication.

The goal of the study was to assess the efficacy of interaction between spinal cord stimulation (SCS) and peripheral nerve field stimulation (PNFS) and to evaluate a new spinal-peripheral neuromodulation method for low back pain. ⋯ Simultaneous use of SCS and PNFS increase efficacy of both methods for axial back pain. The new SPN method showed great potential in providing coverage for back pain.

Spinal cord stimulation (SCS) activates the thalamus, which may be involved in generation of seizures. SCS may therefore influence seizure susceptibility. We investigated the effect of SCS on seizure susceptibility when performed at low frequency (4 Hz) and a frequency in the typical range of SCS treatment (54 Hz). ⋯ Low-frequency SCS is proconvulsive in rats. Further research needs to investigate if this also applies to humans.

Comparative Study
Awake vs. asleep placement of spinal cord stimulators: a cohort analysis of complications associated with placement.
Patients will typically undergo awake surgery for permanent implantation of spinal cord stimulation (SCS) in an attempt to optimize electrode placement using patient feedback about the distribution of stimulation-induced paresthesia. The present study compared efficacy of first-time electrode placement under awake conditions with that of neurophysiologically guided placement under general anesthesia. ⋯ Non-awake surgery is associated with fewer failure rates and therefore fewer re-operations, making it a viable alternative. Any benefits of awake implantation should carefully be considered in the future.
